Application filed March 31, 1921.

To all whom it may concern Be it known that I, Dr. THnorriiLn Gain LARD, citizen of the Republic of Switzerland, residing at Territet, Switzerland, have in.- vented a new and useful Improvement in Presses for Making Pastils and Other Similar Products (for which I have filed application in Switzerland June 11, 1919); and I do hereby declare the following to be a full, clear, and exact description of the same.

In presses for making pastils as have hitherto been proposed the matrices act ver tically; this has the drawback that the substance constituting the pastils often adheres to the matrices and the pastils have not a well defined shape when leaving the latter; it is often necessary to use subsidiary means for obtaining pastils of suitable shape.

The machine according to the present invention allows of obtaining directly clean, smooth pastils, whatever the substance used may be, and this, without the necessity of elmploying an exaggerate pressure which has t e solubility of the pastil.

One mode of construction of an application according to the present invention is illustrated, by way of example, in Figs. 1 and 2 of the accompanying drawings.

Referring to the drawings, D is a perforated steel disc adapted to receive the substance from which the pastils are made, which substance is directed therein from B through a channel G. The disc D is fixed on to the axle A of the machine which may be driven either by hand or by means of a motor.

Above and below the said disc D two other perforated discs D and D are situated; cylindrical rods l and P are inserted in the holes of the discs D and D which rods act as pistons and pass through the holes of the first disc D where they compress at P the substance to planes P and P which act upon their free ends. The said discs are fixed on the same axle A on which the first disc D is fixed. An arrangement of three discs is thus obtained which discs rotate together with the axle A, the middle disc receiving the substance which is to form the pastils, whilst the two other act as a guiding member for the pistons that compress the substance; the motion of the pistons is adjusted so as to great drawback of being harmful to the be treated, and driven for this purpose by means of adjustable inclined Serial No. 457,355.

give exactly the desired degree of compression by means of the inclined planes which are fixed on the machine, but are' however, adjustable at will. When the pastil has just been finished the lower piston pushes it out from the disc D the pastil is moved aside from the hole which it has just left by means of a projection that causes its fall either directly into a tube or box which serves for its final packing, or into a case where they accumulate.

An additional movement of rotation is imparted to the said pistons around their own axes during their ascending and descending displacements inside the discs D D and D to this end, they are provided with pinions p gearing with a toothed segment S fixed on one of the pillars of the machine (see Fig. 2) or on a central toothed wheel fixed on the frame of the latter. Lastly, the pistons P may be constructed in such a manner that their ends shall be provided with removable members allowing of obtaining several different diameters or heights; in the latter case, the disc D is also constructed in such a manner as to receive removable sockets for the passage of the pistons P corresponding to the diameters of the modified ends of the latter.

It is to be understood that the movement of rotation of the pistons may be combined so as to be continuous for the full stroke of the pistons, either alternately in one direction, then in the other or for a portion only of their stroke.

I claim:

1. A tablet press including a rotary mold table provided with an aperture, supporting elements rotatable with said table, rotatable and axially movable plungers carried by said supporting elements and adapted to compress material arranged in said aperture, fixed cams cooperating with said plungers for moving the same axially, pinions fixed to said plungers, and fixed gears engageable with said pinions for rotating said plungers as the same move toward one another.

2. A tablet press including a rotatable shaft, a mold table fixed to said shaft and provided with an aperture adapted to re ceive material to be pressed,supporting elements fixedly mounted on said shaft, rotatable and axially movable plungers carried by said supporting elements and having end portions adapted to enter said aperture for compressing the material therein, fixed cams,

cooperating with said plungers for moving the Seine toward one ainothei, Ifieehs for ineving said plungers away from one another, pinions fixedly mounted on said plungers, and fixed gears cooperating with said pinions to rotate said plungers as they move toward one anothef.

Intestimony whereof, I h eve signed my name to' this 'speoificatioxi in the presence of tWo subscribin witnesses.
